So basically they took a moderate restored 27 with color touch around all edges, cut away the color touch and all underlying original paper, leaf cast out those areas and recolored them and trimmed them to simulate a basic size parameter. If that is correct the the 9.6 extensive, while certainly very visually appealing, is significantly less original than the 6.5 moderate. If one applies water to the 9.6 the leaf-cast area should fall away leaving a mangled edged book similar to the attachment. It should be worth significantly less.
Thank you kindly for your comment Mr. Bedrock. Just to clarify, the 27 prior to our resto was a CGC 6.5 B-5. This means it was previously Extensive (and more/less Amateur). 5 is the maximum CGC designation for degree of resto. Previous resto had a form of irreversible mending around 75% of the book's interior cover perimeters. Irreversible meaning permanent, meaning not removable in water, meaning it had to be chiseled/scraped off. This mending caused decent warping in the book. In order to grade high, the book cannot cockle or warp and must be seamless. It was necessary to extract and re-cast using a slurry containing proper amounts of conservation grade additives to prevent shrinkage over time. Nobody likes shrinkage.
Best,

bedrock is correct if it was mod...but it was already extensive so likely your extensive is no more work, just makes it look better...
a question, if I may have your attention for a moment....approx. how much of the front cover surface area is "original" and how much is painted over...I think for me, that is the question I would like to know the answer too...
if it is 5% or 10%, then 90-95% of cover is original, I would consider bidding/buying... but if it is 15%+ to ?, that is where I wish the detail was known...and since you did the work, you know the detail, so would appreciate if you would elaborate
